lib: sbi: fix GLOBAL_PLAT_DEFINE

2024-12-15T06:22:57Z

Fix GLOBAL_PLAT_0_START/END definitions. The specification states that the beginning of the range is 0xc000 and the end is 0xffff. Reported-by: Andrew Jones Signed-off-by: Clément Léger Reviewed-by: Anup Patel

lib: sbi: Implement SBI MPXY extension

2024-12-06T03:56:52Z

Implement the SBI MPXY extension which provides an SBI interface to the supervisor software for send messages via MPXY framework. Signed-off-by: Rahul Pathak Co-developed-by: Anup Patel Signed-off-by: Anup Patel

lib: sbi: Add SBI Message Proxy (MPXY) framework

2024-12-06T03:56:50Z

Introduce SBI Message Proxy (MPXY) framework which allows platform specific code or drivers to register message protocol specific channels. This framework enables the supervisor software to send messages belonging to different message protocols via OpenSBI firmware.

lib: sbi_pmu: Add SBI PMU event info function details.

2024-12-02T04:22:52Z

The SBI v3.0 introduced a new function to query about the events without invoking CFG_MATCH. This allows supervisor software to identify which events are supported on the platform with single SBI call instead of a CFG_MATCH for each event. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: sbi_pmu: PMU raw event v2 support

2024-12-02T04:22:04Z

As per the updated ISA specification and SBI PMU v3.0, lower 56 bits are available for the platform to implement mhpmeventX encoding. Implement the PMU raw event V2 support defined in SBI v3.0 which allows more bits for platforms to encode the raw events. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: sbi: send a double trap SSE event to supervisor

2024-10-25T18:28:39Z

In case the double trap handler is called and the double trap happened in supervisor mode, send a double trap SSE event. NOTE: this commit depends on the ratification of the new SSE event id for double trap [1].

lib: sbi: Add support to mask/unmask SSE events

2024-10-25T17:34:43Z

Add functions to globally mask/unmask supervisor software events on the calling hart. Signed-off-by: Himanshu Chauhan Reviewed-by: Anup Patel

lib: sbi: fwft: add support for SBI_FWFT_POINTER_MASKING_PMLEN

2024-09-23T12:20:40Z

Add support for controlling the pointer masking mode on harts which support the Smnpm extension. This extension can only exist on harts where XLEN >= 64 bits. This implementation selects the mode with the smallest PMLEN that satisfies the caller's requested lower bound. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: sbi: add support for firmware features extension

2024-06-19T12:39:22Z

This extension allows the software running in supervisor mode to control the behavior of various features of the SBI [1]. Implement the support for such extension. Link: https://lists.riscv.org/g/tech-prs/message/924 [1] Signed-off-by: Clément Léger Reviewed-by: Anup Patel
